ELEcTRIc-oEnERATon SUPPORT.

Specification of Letters Patent. I Pate itedOct, 14, 1919,

Application filed October 29, 1317. Serial No. 199,141. I

To all whom it may concern:

Be it known that I, CHARLES H. QUINN,

I a citizen of the United States, residing at sible chance ofdisengagement.

Roanoke, in the county of Roanoke and State of Virginia, have inventedcertain new and useful Improvements in Electric-Gen- .erator Supports;and I do hereby declare the following to be a full, clear, andexactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to means for suspending car axle driven dynamosfrom the in connection with the accompanying drawings which have beenchosen for the purpose of illustrating a single embodiment of. myinvention, and in which Figure 1 is a top plan view of a portion of acar truck showing the invention applied thereto,

Fig. 2 is a View partially in section and partially in side elevation ofthe structure shown in Fig. 1, v

Fig. 3 is an end elevation of the structure shown in Fig. 1, portionsof'the truck being omitted for the sake of clearne ss, and

Fig.4i a fragmentary detail showing a spring tensioning device.

Throughout the specification and draw- I ings like parts are designatedby like reference characters.

The numeral 1 designates the frame of the car truck provided with sidemembers 2 and v a cross or end member 3, only one of the latter beingillustrated. A pair of suspension bars 4 are connected to the sidemembers 2 by means of bolts 5, 5. :A block 6 maybe interposed betweeneach suspension bar. and

the adjacent side frame member so as to space the bars inwardly of theside frame members 2, if desired. The suspension bars 4 are forconvenience formed as rectangular bars or plates and as illustrated areadapted to extend a short distance beyond the end member 3 of the truckframe. Braces 50 areprovided for stiffening the outer ends of the bars 4against lateral bending these being bolted to the frame 1 by means ofthe bolts 51 and to the bars 4 by means of the bolts 52.

The electric generator or dynamo supporting frame or cradle 7 preferablycomprises a channel bar 8, the flanges 9 thereof extending downwardly.This bar 8 is provided with upwardly extending legs 10, which mayconveniently be formed by bending the ends of the channel 8substantially at rightangles to'the main body of said bar. In order. tocounteract any tendency of the bar 8 to deform at the ends, I preferablyprovide a stiffening member 11, in the form of a plate at each corner,these stiflening members being rigidly riveted at opposite ends to theweb of the channel bar on opposite sides of the bend or angle. To theupwardly extending ends 10 of the bar 8 are rigidly connected,preferably by means of rivets 12, hangers or yokes 13 which may comprisewrought iron bars bent to form an eye or loop 14, the free ends of theloop being adapted to extend on opposite sides of the web of the bar 8and through these free ends and the intervening web are adapted toextend the connecting rivets 12 which rigidly tie these parts together.Each of the hangers 13 is provided adjacent its upper end 15 with apivot member adapted to cooperate with the pivot member 16 which isformed on the pivot brackets 17. Each pivot bracket 17 preferablycomprises a saddle or bifurcated plate 18 which is adaptedv to straddlethe outwardly projecting end of one of the suspension bars, 4 to whichthe bracket 17 is adjustably connected, as will be hereafter more fullyset forth, by means of the bolts 19. The form of pivotal connectionbetween each bracket 17 andthe adjacenthanger 13 may, and preferablydoes comprise a bolt 20 which is adapted to extend through'alinedopenings2l and 22 in the hangers 13 and brackets 17 respectively.

As will be clearly seen from the disclosure, particularly Figs. 2 and 3,the opening 14 in the hangers 13 while of suflicientwidth to. allow thebrackets 17 to be inserted within the loop of the hanger 13 is, however,of less width than the length of the bolts 19 which connect the bracketsto the suspension rods 4. It will be evident that after the hangers andbrackets are pivotally connected by meansof the bolts 20, that thesec'uring'bolts 19 will prevent the accidental disengagement of thehangersand brackets shouild eitheii bolt 20 break.

Intermediate the ends of channeland on the upper side thereof, isrigidly" connected .a plate 24%- to receive the -dynamo or electricgenerator 25,,whichis diagram matically illustrated by dotted lines, and

between the plate and oneendoi therbar; 8 and in the same plane withthepulley 26 ofthe generator 25 is the tensionspringseat 27 This springSeatyQTpreferably comprises an angledor substantially Lesh-aped platerigidly connectedto the channel means of the rivets 28. In thedownturned end 290i the plate 27 there is provided an I opening30, theinner or truck-adjacent end.

ofv which is enlarged to form a conical: bear,-.

ing 31. Tothe cross member 3 of theftruck frame, is connected thetension rod. yoke 32' whichpreferably comprises a substantially U-shapedmember, the legs 33 of which are I bottommember 34' adjacent the opening35,

the said bracket beingprovided witha, pair of perforated lugs orears3-7.

The tension rod 38 is adapted-" to extend through the alined openings35' in the yoke 32 and the opening 30in the spring seat plate 27, theinner end of the rod beingconnectedito-the bracketv36 by means of thebolt3'9Q The outer end of the rod 38 p'ass'esthrough a bushing 40 whichismountedin the opening 30, the said bushing having-a;

' conical fhead' 41' adapted to'seat in andv choperat'ewith the conicalbearingl gl. Interposed between the bushing 40" and the Weightedadjusting nut 42,which isjthread' ably mounted on the tension iod'adjacentj the yoke'32,'i s the tension spring 43' and the slidingsleeve 44 The device is'connec'ted tothe truck first connecting the-bars4 to the side frames 2. The entire cradle 7 is then connectedjt'o thepivotal brackets 17, after which brackets 17; are slidably mounted. onthe projecting ends ofth'e-rods l, jThel'cradle' isthen'adg' j'usted inparallelismfwith the'car'aXle and holes are bored throughthe bars 4" toal'ine with the openings inthe' brackets 17. and through these almedopenings are inserted the bolts 19'. This methodof connectionpermits ofthe ready adjustment of the cradle to meet all the requirements ofservice. I

i The pulley 26 6f the generator is operativel'y connected to the pulley46 which is meuntedt onathe ear a-Xle 47 by means of the belt 45. Itwill be seen on an inspection "oi -Fig: l thatthe spring tensio-ningdevice is located in the vertical plane of the pulleys 26311d462-- By solocating thetensioni-ng device in linewith the belt center, I avoid alleccentric or twisting movement in the suspension frame or cradle and bylocating v the tensioning, device betweenf't h e truck frame and. thed'ownturnedl end of the, plate 27f sherten-v the over-alllengthof thed'evice and protect the" tensioning device from accidental. breakage;
